Dysprosium

CAS: 7429-91-6
Molecular Formula: Dy
Molecular Weight: 162.5
Product description:Insoluble in cold water and hot water, but soluble in acid. Dark surface oxidation in air. Is the more active metal. Common oxidation state + 3. With sulfur, phosphorus and other non-metallic heating reaction. But with many metals to form alloy. Strong ability to capture thermal.1) as a department of ndfeb permanent magnet additive is used, in this kind of magnets to add 2 ~ 3% of dysprosium, the coercive force can be improved, the demand for dysprosium is not big, but with the increase of demand ndfeb magnet, it becomes necessary to add elements, grade must be in the 95 ~ 99. About 9%, demand is increasing rapidly. Dysprosium (2) as an activator phosphors, trivalent dysprosium is a kind of promising single active ion luminescence center tricolor luminous material, it is mainly composed of two emission band, a yellow light emission, another is blue light emission, mixed dysprosium luminescent material can be used as tricolor phosphors.
